I guess he knew what was wrong. He did not apology to me neither did he talk about it. He called me while I was trying to sleep and asked me to said that three words to him. I told him I wanted to sleep.
Today, everything was all right again. He called me after my dinner and tell me things about my cats and what he ate today. I was trying to watch the TV at the same time not to let him know that I was watching the TV. Soon, he sense that I seems to be busy with something.
